Our invention relates to improvements in a machine for cutting cards from sheet match stock preparatory to having the cardsv made into matches. a Our invention also comprises 5 a step in the art of preparing such stock which afiords an economy in the preparation of the stock. So far as the machine is concerned, the object ofour invention is toproduce a simple and efficient machine which will rapidly out long strips of stock into cards of a desired length. These cards are subsequently made into matches and headed in conventional or preferred ways. The invention Will be better understood from the following description.

Reference is to be had to the accompanying drawings forming a part of this specification,

in which similar reference characters indi cate corresponding parts in all the views.

Figure 1 is a plan view of the machine embodying our invention.-.

Figure 2 is a side elevation. Figure 3 is a broken sectional plan of the machine. Figure 4 is a cross section on the line 4'4= of Figure 3, and

Figure 5 is a broken sectional detail of the knife carrying roller of the cutter.

Y The machine is provided with a suitable frame comprising in the present instance a' bed 10 and supporting legs 11. The bed is 7 shown broken, as in practice it also forms a support for mechanism to perform other work on the stock. c 'u 1 n The sheet stock 12 is usually a wood veneer but it can be any sheet stock, and it is asstated of the thickness of a match, while its width v corresponds to the length of a match. In practice the veneer generally comes "in the form of a roll 12 which is the way it isc-rolled up after being turned ona Veneer lathe, and the roll is mounted on a spool'13 which lies horizontally on the spindle 14'.
